TOBIAS CHNAPKO, 0F MACDONAL'ION, PENNSYLVANIA.

DUMP-GAR.

Application filed April 20, 1918.

To all whom it may concern:

Be it known that I, Tomas CHNAPKO, a subject of the King of Hungary,residing at Macdonalton, in the county of Somerset and State ofPennsylvania, have invented new and useful Improvements in Dump-Cars, ofwhich the following is a specification.

This invention relates to new and useful improvements in doorcontrolling means for dump cars and the principal object of theinvention is to provide means for automatically opening each pair ofdoors of a plurality of chutes located in the bottom of the car.

Other objects 'of the invention are to provide means for actuating saiddevices by an obstruction placed along the track. means for throwingsuch devices into and out of operative position and other means forclosing said doors actuated by another obstruction placed along thetrack.

Another object of the invention is to pro vide a device of thischaracter which is simple and durable in construction, reliable andetiicient in operation and one which can be manufactured and placed uponthe market at a minilnum cost.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts,

to be hereinafter fully described. illustrated in the accompalrvingdrawings and specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote. like orcorresponding parts throughoutthc several views. and in which Figure lis a side view showing the invention in use on a car with the doorsclosed.

Fig. 2 is a bottom plan view.

Fig. 3 is a view similar to Fig. 1 but showing thedo'ors in openposition.

Fig. 4 is a detail view.

Fig. 5 is a side view showing a modificw tion of a device for closingthe doors.

Fig. (3 is a detail view of the arrangement of operating cables orchains.

Fig. 7 shows a modification of an arrange Merit of these cables.

Referring more particularly to these drawings, 1 indicates the car bodyprovided with four dumping chutes These chutes are of wedge shape, asusual, and are each closed by a pair of doors 3 hinged at their upperends: to the bottom of the ca as at Specification of Letters Patent.

4. One door of each pair has a pair of lugs 5 at its free end betweenwhich is pivoted a. latch 6 which is adapted to engage the end of theother door, said end having a keeper 7 thereon with which the latchengages. A spring 8 engages with said latch for forcing the same intoengagement With the keeper on the other door and I prefer to enlarge therear part of said latch as at 9 so that the action of gravity will tendto keep the latch in engagement with the keeper. If desired this part ofthe latch may be weighted. A link or arm 10 is pivoted to one edge ofeach door intermediate its ends and the upper ends of these arms areconnected together by a pin 11 which is movably mounted in a slottedbracket 12. By this means the doors are caused to move in unison and theslot 12 in the bracket. is made of such a length that the arms 10 willprevent the doors from swinging open to a position beyond the vertical,as clearly shown in Fig. 3.

The innermost doors of the two pairs on each side of the car areprovided with latches and I provide means for actuating said latches inunison. These means consist of a rod 13 journaled in brackets latsecured to the under side of the car. This rod is provided with a pairof cranks 15 to which the operating cables or chains are secured. 17indicates brackets secured to the bottom of the car and extendingdownwardly and supporting rollers 18 over which said chains extend. Eachlatch is connected with a crank 15 by a pair of cables, one 'able 16passing upwardly from the latch over one of the pulleys 18 to the crankand the other cable passing upwardly from the latch over another pulleyarranged along side the pulley just mentioned and from this pulley thecable 16 passes to a pulley on the opposite side of the rod 13 and fromthis pulley the cable passes to the crank. lln this way all of the doorswill .be opened sin'ml'taneously by a partial rotation of the rod 13 ineither direction.

The rod 13 is provided with a forked end 13 projecting beyond one Sideof the car and a bar 20 is pivoted in. said forked end. The end of thisbar is adapted to contact with a post 21 located along the track at apoint where it is desired to dump the car so that as soon as the bar 20strikes said post the rod 13 will be given a partial rotation so as toopen all the doors and thus in Fig. 4.

dump the load. I provide means for holding said bar in raised positionso as to avoid danger of the unintentional opening of the doors and suchmeans consists of a spring dog 22 carried by the end of the rod 13 andengaging recesses 23 in the pivoted end of said bar. Said recesses areso located that the bar will be held in vertical position or inhorizontal position. In this latter position the bar will engage theunder side of the rod 13 as shown in dotted lines Slightly beyond thedumping location I provide means for closing the doors, such meansconsisting of an inclined post 2* placed along the track at a suitabledistance from the dumping location and arranged to contact with thefirst door of the series so that said door will be closed by said post,and through the connections before described will close all the otherdoors, the latches being thrown in engaging position when th doors areclosed. w

Fig. 5 shows a modification for closing the doors. In this case the pin11' is extended outwardly beyond the arms 10' so as to contact with aninclined bar 24: supported along the track by means of the posts 25. Inthis form when the car leaves the dumping location the pin 11 willstrike the inclined bar 24 and will be moved up the same and thus moveupwardly in the slot 12". This will cause the doors to swing shut asbefore described to permit the latches to engage the doors to hold themin closed position.

In the modification shown in Fig. 7 instead of the cranks on the rod Iprovide the same with cross bars 26 to which the chains or cables 27 areconnected at the ends thereof. These cables pass downwardly and areconnected with the latches as before described. Other cables 28 areconnected with the ends of the bar 26 but pass in an opposite directionto the cables 27 and are connected with the latches on the other side ofthe bar 13'.

It will thus be seen that as soon as the vertical rod 20 comes againstthe post 21 on the movement of the car to dumping position the doorswill be opened simultaneously to dump the load. Then when the car ismoved from the dumping location all the doors will be closed by theinclined post 2i.

It is thought from the foregoing description'that the advantages andnovel features of my invention will be readily apparent.

I desire it to be understood that I may make such changes in theconstruction and in the combination and arrangement of the severalparts, provided that such changes fall within the scope of the appendedclaims.

Vhat I claim is 1. In combination with a dumping car having a pluralityof chutes in its bottom, of a pair of doors for closing each chute.latch means for said doors, arms connecting each pair of doors togetherfor causing them to move in unison, a rod carried by the bottom of thecar, means located under the car and including flexible elements forconnecting said rod with the latch means to cause said doors to beopened when the rod is partially rotated and an obstruction along thetrack for engaging saidrod to give the same a partial rotation.

52. In combination with a dumping car having 'a plurality of chutes inits bottom, of a pair of doors for closing each chute. arms connectingeach pair of doors together. a latch carried by one door and engagingwith the other door, a rod carried by the car. pulleys also carried bythe car, a pair of cables connecting each latch with the rod and soarranged in respect to the said rod and pulleys that the latch will bemoved into inoperative position on the movement. of the rod in eitherdirection and means for oscillating said rod.

3. In combination with a dumping car. having a plurality of chutes inits bottom, of a pair of doors for closing each chute, an oscillatingrod carried by the car bottom, means operable by the said rod foropening all the doors simultaneously, a bar pivoted to the end of saidrod and adapted to engage an obstruction along the track and springmeans for holding said bar in either its raised orlowered position.

In testimony whereof I aflix my signature.

TOBIAS CHNAPKO.
